TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioners, in particular to an air conditioner. BACKGROUND

[0002] An air conditioner is a commonly used device for adjusting indoor temperature, and the rationality of the air duct arrangement structure design has a great influence on the air guiding performance of the air conditioner, and also affects the use comfort of the user. If the utilization rate of the air duct is not high, the performance of the air conditioner will also be affected.

[0003] The air volume and the overall performance of the air conditioner provided by the related art still need to be improved. SUMMARY

[0004] The problem solved by the present application is to improve the air volume of the air conditioner, and thus improve the performance of the air conditioner to improve the user experience.

[0005] To solve the above problems, the present application provides an air conditioner, comprising:

[0006] A shell, the shell is provided with an air outlet;

[0007] A cross-flow fan blade, which is rotatably arranged in the shell;

[0008] A sweeping blade, which is movably arranged in the shell and is configured to swing along the extension direction of the rotation axis of the cross-flow fan blade to adjust the air outlet direction; wherein,

[0009] The sweeping blade has a first end adjacent to the air outlet and a second end away from the air outlet, and the distance between the first end and the second end in the radial direction of the cross-flow fan blade is the width of the sweeping blade;

[0010] The ratio of the diameter of the cross-flow fan blade to the width of the sweeping blade is 1.7-2.

[0011] By configuring the ratio of the diameter of the cross-flow fan blade to the width of the sweeping blade to be 1.7-2, the configuration of the cross-flow fan blade and the sweeping blade is optimized to facilitate the improvement of the sweeping range of the sweeping blade, the improvement of the air volume, and the improvement of the overall performance of the air conditioner, thereby improving the user experience.

[0012] In an optional embodiment, the ratio of the diameter of the cross-flow fan blade to the width of the sweeping blade is greater than 1.7 and less than 2.

[0013] By optimizing the ratio of the diameter of the cross-flow fan blade to the width of the sweeping blade, it is ensured that the sweeping range of the sweeping blade is improved, and thus a larger air supply range is realized to ensure the utilization rate of the air volume.

[0014] In an optional embodiment, along the radial direction of the cross-flow fan blade, the distance between the second end pointing to the outer periphery of the cross-flow fan blade is the distance between the cross-flow fan blade and the sweeping blade, and the distance between the cross-flow fan blade and the sweeping blade is 15-20 mm.

[0015] With the diameter of the cross-flow fan blade and the width of the sweeping blade at a certain ratio, by adjusting the relative position between the cross-flow fan blade and the sweeping blade, the spacing between the cross-flow fan blade and the sweeping blade is configured to be 15-20 mm, which further optimizes the air outlet path, improves the utilization rate of air volume, ensures the increase of air volume, and thus improves the overall performance of the air conditioner and the user experience.

[0016] In an optional implementation, the distance between the cross-flow fan blades and the sweeping blades is greater than 15 mm and less than 20 mm. This ensures that the gap between the cross-flow fan blades and the sweeping blades is at an optimized value, thereby optimizing the air outlet path, increasing air volume, and improving the overall performance of the air conditioner.

[0017] In an optional embodiment, the air conditioner further includes a volute, which is disposed within the housing. The air conditioner can utilize the volute to generate an eccentric vortex to deliver air.

[0018] In an optional embodiment, the volute tongue has a first side facing the sweeping blade and a second side away from the sweeping blade, the second side having a third end adjacent to the cross-flow fan blade; along the radial direction of the cross-flow fan blade, the distance between the third end and the outer periphery of the cross-flow fan blade is the distance between the cross-flow fan blade and the volute tongue; the distance between the cross-flow fan blade and the volute tongue is 3-5.5 mm.

[0019] By adjusting the position of the cross-flow fan blades, the gap between the cross-flow fan blades and the volute tongue is optimized, thereby optimizing the air outlet path, increasing air volume, improving the overall performance of the air conditioner, and enhancing the user experience.

[0020] In an optional implementation, the gap between the cross-flow fan blades and the volute tongue is greater than 3 mm and less than 5.5 mm. Optimizing the gap between the cross-flow fan blades and the volute tongue ensures an optimized airflow path, increases air volume, and improves the utilization rate of the airflow in the air conditioner.

[0021] In an optional embodiment, the air conditioner further includes a guide sidewall disposed within the housing, a first air outlet duct formed between the volute tongue and the guide sidewall, and a sweeping blade disposed within the first air outlet duct.

[0022] By oscillating the sweeping blades located in the first air outlet duct, the air conditioner can be ensured to have a sufficiently large sweeping range, thereby improving the user experience.

[0023] In an optional embodiment, a second air outlet duct is formed between the guide sidewall and the cross-flow fan blade, and the first air outlet duct and the second air outlet duct are connected to form an air outlet duct.

[0024] This design ensures that the cross-flow fan blades can drive the airflow within the casing to flow smoothly, which in turn helps to ensure the air volume of the air conditioner.

[0025] In an optional implementation, the air conditioner is a floor-standing air conditioner. Attached Figure Description

Detailed Implementation

[0032] Air conditioners are commonly used devices for regulating indoor temperature. The rationality of their air duct layout design has a significant impact on the air guiding performance of the air conditioner, and also affects user comfort. If the utilization rate of the air duct is low, the overall performance of the air conditioner will also be affected.

[0033] The inventors discovered that unreasonable dimensions of the cross-flow fan blades and the sweeping blades can easily lead to a small sweeping range of the sweeping blades, which is not conducive to improving the air volume. Moreover, unreasonable placement of the cross-flow fan blades and the sweeping blades can create an air outlet path that is not conducive to air outlet, which can also make it difficult to improve the air volume, resulting in poor overall performance of the air conditioner and a poor user experience.

[0034] The air conditioner in this embodiment can increase airflow, thereby improving the overall performance of the air conditioner and enhancing the user experience.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Please refer to Figure 1 This embodiment provides an air conditioner 010, which can be used to heat or cool air in order to regulate the ambient temperature.

[0037] It should be noted that the air conditioner 010 in this embodiment refers to a floor-standing air conditioner, i.e., a floor-standing indoor unit; of course, in other embodiments, the air conditioner 010 may refer to both the indoor unit and the outdoor unit used in conjunction with it. In other embodiments, the air conditioner 010 may also refer to a wall-mounted indoor unit, which is not specifically limited here.

[0038] The air conditioner 010 includes a housing 100 and an evaporator 200. The housing 100 is provided with an air inlet 111 and an air outlet 121. The evaporator 200 is disposed inside the housing 100 and close to the air inlet 111. The evaporator 200 is used to exchange heat with the air that enters the housing 100 through the air inlet 111, so that the heat-exchanged gas is blown out from the air outlet 121 to achieve the function of regulating the ambient temperature.

[0039] It should be noted that the type of evaporator 200 can be selected as needed, such as tube-plate type, stacked type or tube-strip type, etc., without specific limitations here.

[0040] In this embodiment, the housing 100 is generally cylindrical, so that the air conditioner 010 is generally cylindrical in shape.

[0041] Of course, in other embodiments, the housing 100 may also be an elliptical cylinder, or approximately a quadrangular prism, etc., and no specific limitation is made here.

[0042] The structure of housing 100 can be configured as needed; please refer to the following: Figure 1 The housing 100 in this embodiment includes a rear panel 110 and a front panel 120. The rear panel 110 and the front panel 120 are fastened and connected. The rear panel 110 is provided with an air inlet 111 and the front panel 120 is provided with an air outlet 121.

[0043] The connection method between the front panel 120 and the rear panel 110 can be selected as needed. For example, one of the front panel 120 and the rear panel 110 may be provided with a locking tooth, and the other of the front panel 120 and the rear panel 110 may be provided with a locking groove, with the locking tooth engaging with the locking groove; or, one of the front panel 120 and the rear panel 110 may be provided with a sliding groove, and the other of the front panel 120 and the rear panel 110 may be provided with a sliding member, with the sliding member slidingly engaging with the sliding groove; or, the front panel 120 and the rear panel 110 may be connected by fasteners such as bolts, without specific limitations.

[0044] Furthermore, the front panel 120 and the rear panel 110 are fastened and connected to form an assembly space, within which the evaporator 200 is disposed; thus ensuring the ease of assembly of the air conditioner 010.

[0045] Please refer to Figure 1 The air conditioner 010 in this embodiment also includes a cross-flow fan blade 300, which is rotatably disposed within the housing 100; specifically, the cross-flow fan blade 300 is disposed within the assembly space. The cross-flow fan blade 300 is used to blow the gas inside the housing 100 out from the air outlet 121.

[0046] It should be noted that by placing the cross-flow fan blade 300 within the assembly space formed between the front bulkhead 120 and the rear bulkhead 110, the ease of assembly of the cross-flow fan blade 300 is ensured, and the cross-flow fan blade 300 is also ensured to reliably drive the airflow within the housing 100.

[0047] It should also be noted that the air conditioner 010 also includes a drive assembly (not shown in the figure), which is connected to the cross-flow fan blade 300 for driving the cross-flow fan blade 300 to rotate, thereby driving the airflow to flow towards the air outlet 121.

[0048] Please continue to refer to Figure 1 The air conditioner 010 in this embodiment also includes a sweeping blade 400, which is movably disposed in the housing 100 and is configured to swing along the extension direction of the rotation axis of the cross-flow fan 300 to adjust the air outlet direction.

[0049] Furthermore, the air sweeping blades 400 are positioned adjacent to the air outlet 121; in this way, the air outlet direction can be reliably adjusted by the swinging of the air sweeping blades 400, thereby ensuring the comfort of the user experience and meeting the user's needs.

[0050] It should be noted that the rotation axis of the cross-flow fan blade 300 in this embodiment extends in the vertical direction, and the sweeping blade 400 swings in the vertical direction, that is, the sweeping blade 400 can swing in the up and down direction so that the air conditioner 010 can achieve up and down air sweeping, thereby meeting customer needs.

[0051] Of course, in other embodiments, the rotation axis of the cross-flow fan blade 300 extends in the horizontal direction, and the sweeping blade 400 can also be configured to swing in the horizontal direction, that is, the sweeping blade 400 can swing in the left and right directions so that the air conditioner 010 can achieve left and right sweeping, thereby meeting customer needs.

[0052] It should also be noted that the terms such as vertical and horizontal are based on the relative positions of the air conditioner 010 when it is in use, in its placement and assembly state.

[0053] The air conditioner 010 in this embodiment also includes a sweep drive assembly (not shown in the figure). The sweep drive assembly is in transmission cooperation with the sweep blade 400 and is used to drive the sweep blade 400 to swing so as to adjust the sweep direction.

[0054] Please refer to Figure 1 The air conditioner 010 in this embodiment also includes an air guide device 500, which is disposed on the housing 100 and located at the air outlet 121. The air guide device 500 is distributed on the side of the sweeping blades 400 facing the air outlet 121. The air guide device 500 is used to guide the airflow blown from the air outlet 121 to flow in a preset direction to meet user needs and ensure the practicality of the air conditioner 010. It should be noted that the structure of the air guide device 500 is similar to that of related technologies and will not be described in detail here.

[0055] Please continue to refer to Figure 1 In this embodiment, the ratio of the diameter A of the cross-flow fan blade 300 to the width B of the sweeping blade 400 is 1.7-2. In this way, by adjusting the diameter of the cross-flow fan blade 300 and the width of the sweeping blade 400, the ratio between the diameter of the cross-flow fan blade 300 and the width of the sweeping blade 400 is kept within an optimal range, which helps to improve the sweeping range of the sweeping blade 400, thereby ensuring the air volume of the air conditioner 010, improving the overall performance of the air conditioner 010, and enhancing the user experience.

[0056] Furthermore, the sweeping blade 400 has a first end 410 adjacent to the air outlet 121 and a second end 420 away from the air outlet 121. The distance between the first end 410 of the sweeping blade 400 and the second end 420 of the sweeping blade 400 along the radial direction of the cross-flow fan blade 300 is the width of the sweeping blade 400.

[0057] In a preferred embodiment, the ratio of the diameter A of the cross-flow fan blade 300 to the width B of the swept blade 400 is greater than 1.7 and less than 2. In this way, by optimizing the ratio of the diameter of the cross-flow fan blade 300 to the width of the swept blade 400, the sweeping range of the swept blade 400 is improved, thereby achieving a larger air supply range and ensuring the utilization rate of air volume.

[0058] Please continue to refer to Figure 1 In this embodiment, the distance C between the cross-flow fan blade 300 and the sweeping blade 400 is 15-20 mm. By optimizing and adjusting the relative position between the cross-flow fan blade 300 and the sweeping blade 400, the gap between the cross-flow fan blade 300 and the sweeping blade 400 can be optimized, thereby optimizing the air outlet path, increasing the air volume, and improving the overall performance of the air conditioner 010.

[0059] Furthermore, along the radial direction of the cross-flow fan blade 300, the distance between the second end 420 of the swept blade 400 and the outer periphery of the cross-flow fan blade 300 is the distance between the cross-flow fan blade 300 and the swept blade 400.

[0060] In a preferred embodiment, the distance C between the cross-flow fan blade 300 and the sweeping blade 400 is greater than 15 mm and less than 20 mm; this setting ensures that the gap between the cross-flow fan blade 300 and the sweeping blade 400 is at an optimized value, thereby optimizing the air outlet path, increasing air volume, and improving the overall performance of the air conditioner 010.

[0061] Please refer to Figure 1 and Figure 2 The air conditioner 010 in this embodiment also includes a volute 600, which is disposed inside the housing 100; the air conditioner 010 can use the volute 600 to generate an eccentric vortex to deliver air.

[0062] The structure of the volute tongue 600 and the way it is set in the housing 100 are similar to those of related technologies, and will not be described in detail here.

[0063] The gap D between the cross-flow fan blade 300 and the volute tongue 600 is 3-5.5 mm. By adjusting the position of the cross-flow fan blade 300, the gap between the cross-flow fan blade 300 and the volute tongue 600 can be optimized, thereby optimizing the air outlet path, which is conducive to increasing air volume, thus improving the performance of the air conditioner 010 and enhancing the user experience.

[0064] Furthermore, the volute tongue 600 has a first side 610 facing the sweeping blade 400 and a second side 620 facing away from the sweeping blade 400. The second side 620 has a third end 621 adjacent to the cross-flow fan blade 300. Along the radial direction of the cross-flow fan blade 300, the distance between the third end 621 and the outer periphery of the cross-flow fan blade 300 is the distance between the cross-flow fan blade 300 and the volute tongue 600.

[0065] In a preferred embodiment, the distance D between the cross-flow fan blade 300 and the volute tongue 600 is greater than 3 mm and less than 5.5 mm. This optimizes the gap between the cross-flow fan blade 300 and the volute tongue 600, thereby ensuring an optimized air outlet path, increasing air volume, and improving the air volume utilization rate of the air conditioner 010.

[0066] The cross-flow fan blade diameter to the sweeping blade width ratio of the air conditioner provided by the related technology is 2.7, the distance between the cross-flow fan blade and the sweeping blade is 20.2 mm, and the distance between the cross-flow fan blade and the volute is 6.1 mm; and the air volume comparison between the air conditioner provided by the related technology and the air conditioner of this embodiment is shown in Table 1 and... Figure 3 The velocity cloud map of the air outlet of the air conditioner in this embodiment is shown in [reference needed]. Figure 4 .

[0067] Table 1. Comparison of air volume between the air conditioner 010 provided in related technologies and the air conditioner 010 of this embodiment.

[0068]

[0069] According to Table 1 and Figure 3 The results show that, through the optimized adjustment of the ratio of the diameter of the cross-flow fan blade 300 to the width of the sweeping blade 400, and the adjustment of the position of the cross-flow fan blade 300, the air volume of the air conditioner 010 is significantly improved.

[0070] Please refer to Figure 1 and Figure 2 The air conditioner 010 in this embodiment also includes a guide sidewall 130, which is disposed within the housing 100. A first air outlet duct 141 is formed between the volute 600 and the guide sidewall 130, and a sweeping blade 400 is disposed within the first air outlet duct 141. By swinging the sweeping blade 400 disposed in the first air outlet duct 141, the air conditioner 010 can be ensured to have a sufficiently large sweeping range, achieving air delivery to a larger space, thereby improving the user experience.

[0071] Optionally, the flow guide sidewall 130 may be connected to at least one of the front bulkhead 120 and the rear bulkhead 110 to ensure the stability of the flow guide sidewall 130 in the housing 100, thereby reliably guiding the airflow.

[0072] Furthermore, a second air outlet duct 142 is formed between the guide sidewall 130 and the cross-flow fan blade 300, and the first air outlet duct 141 and the second air outlet duct 142 are connected to form the air outlet duct 140. This arrangement ensures that the cross-flow fan blade 300 can drive the airflow within the housing 100 to flow smoothly, thereby helping to ensure the air volume of the air conditioner 010.

[0073] The working principle of the air conditioner 010 in this embodiment includes: air enters the housing 100 from the air inlet 111 and can exchange heat with the evaporator 200 inside the housing 100. After heat exchange, the air is blown out from the air outlet 121 under the drive of the cross-flow fan blade 300. During the blowing of the airflow, the sweeping blade 400 can swing in the up and down direction so that the airflow is blown into a wider space.

[0074] In summary, the air conditioner 010 of the present invention can effectively ensure a larger sweeping range, increase air volume, ensure air volume utilization, improve the overall performance of the air conditioner 010, and enhance the user experience by optimizing the ratio of the diameter of the cross-flow fan blade 300 to the width of the sweeping blade 400, and by adjusting the position of the cross-flow fan blade 300, thereby optimizing the gap between the cross-flow fan blade 300 and the sweeping blade 400, as well as the gap between the cross-flow fan blade 300 and the volute tongue 600.

[0075] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
